Canadian MMs: oil pressure gage markings?

[TripleTransAm]

Calling all Canuck MMs: are your oil pressure gages metric (kPa) or imperial (psi)?

Stopped by the dealer to pick up some parts for my foglamp/highbeam override and wanted to buy a spare oil pressure gage to gut for the Autometer replacement. The parts computer had both a Canadian and a US spec oil pressure gage, so I a$$umed it was due to the metric vs. imperial markings. For some reason, the US version is listed as not available yet (?) , whereas the Canadian version is available but needs to be shipped up from the States (WTF?).

I get home and check my own gage... PSI markings! WTF?

So I call up the parts dude, and we can't figure it out. Turns out there's also a Canadian AND a US version of the voltmeter too... like, who ever heard of a metric volt?????

Can anyone shed some light on this confusion?

Why, certainly...

Metric volts are what AC batteries put out...duh... :rolleyes:

I'm tired... I had to think twice about that comment! LOL!

I checked mine out on the weekend. I have NO markings, or I need new glasses. (Mom said it would make me go blind...)

I was in a speed shop looking for new gauges too. My oil pressure has markings 40 - 50 - 60 - 70 - 80 - 90 - 100, but no units, KPa pr PSI. Just numbers.

My battery meter is listed in Joules though :-)

Mine doesn't either... the number range does indicate it's in psi, though... 70 kPa would not be something to brag about, to be honest. :D I don't have the exact numbers handy, but 200 kPa is about 30 psi.

So you've got imperial markings as well... so what the heck is the difference between the US and the Canadian versions of this gage, as listed on the Ford parts system?

And here I was thinking my car was unique... (ie. metric dash with imperial oil gage).

BTW, anyone who can help in describing why the Ford parts system has two different parts listed for the gage, I'd appreciate it... I want to get the conversion done before next week and want to know what to order.

Could the pressure gauge be in percent?

And why is my fuel gauge in hogsheads-to-the-rod? :lol:

Doubt it... percent of what? Most oil pressure specs indicate a range of acceptable oil pressures at a given RPM, and this is to account for production variations and oil viscosity ratings. Add to this the fact that an engine's oil pressure will change with oil temperature, and over the engine's lifetime will decrease with normal wear and tear.

Edit: not to mention that most stock MM owners would be worried if they only saw at ~70 percent of oil pressure... what happened to the other 30?

And this still wouldn't indicate why a US percent would be different from a Canadian percent. ;);)

Maybe the Canadian oil pressure gauge is a real one?
Check the part number of the sending unit.
Volt meter,I don't know....

[TripleTransAm]

I can assure you, what I've got as an oil pressure gage in my MM is NOT real. ;)

Canadian gages - by Canadian law - must display the ISO symbol for oil pressure ??and volts??. The Stock gage faces from Autometer (NOT exactly the same as the Autometer gages supplied to Ford for the Marauder) do NOT have ISO symbols on them.

Soooooooo
Two sets of gages. One for USA, where ISO symbols are not a legal requirement, so the gages look more like the ones you can buy at your local speed shop, and another set for Canada, so they meet the letter of the law there.

Mine's got a little picture of an oilcan and that's all.

Wow. Interesting. So the US Marauders actually DO get a different gage face than the Canadian versions, according to this!

Sure enough, I went and checked out some photos I pilfered from the net while I was pondering my decision to purchase, and compared with a photo of my own gages... son of a b****, I never would have guessed!!

I wish I'd known about this last week, I could have ordered the Canadian version and had it by today. Oh well, I'm off to an open-late dealer parts department to pick up the sender, at least I can get started with that part of the mod. Overall, my own dealer has given me tremendously good service, but the parts guy has let me down 3 times. I'll have to have a chat with him tomorrow morning when I bring my car in for the squeaky seat fix. :mad:

Thanks so much for clueing me in on this info!!

[WolfeBros]

Interesting info. Who woodathunkit ?
Makes you wonder what if anything else is different?

[Dr Caleb]

See! That's what I'm talking about. The gauge is marked 0 - 100, no units. Yours is reading about 67.5. It shows the oil symbol, but no calibration units.

I'm thinking percent of maximum oil pressure. I've had other V-8's that read over 100 PSI of oil pressure, so ~70% would be about right at idle.

Not that the gauge actually does anything though...

[cyclone03]

TooMany Trans Ams,
Is the US version the pic you nabbed from the web?
Why I ask is the readings,the oil pressure is showing below 60psi and the volts almost 15!
I wonder if those are real working gauges and not iddiot gauges that come stock.
On the other hand the canadian pic shows the exact reading I see on my oil pressure gauge anytime the engine is running,and the voltage is also what I would call normal.

[TripleTransAm]

Yes, the US version (I guess that's what it is) is the one I got from the web. From the looks of it, those pics were taken from an ebay auction earlier in the year, from Texas if I remember correctly.

Yeah, I noticed the high voltage as well, but it's possible to get readings that high when the ambient temp is cool and the car is just fired up. I see this behavior on all my cars with real voltmeters. As for the oil pressure, I'm seeing around 60 psi in that picture, the mark between 50 and 75 supposedly being 62.5 psi. Doesn't matter, these gages are simple on-off types, as confirmed to me by my tech this morning (as a formality, since I had to formally 'raise a complaint' about inaccurate pressure readings so that they will accept my sender/gage modification).

Here's another shot I nabbed from another ebay auction, sometime this past spring.

Of course, there is no guarantee that these are the factory gages and that a swap hadn't already been done... I'm counting on you stock US-cars to back me up on these US-gage pics.


edit: rereading your post, cyclone, I guess you meant maybe the US-photo I originally posted was of a car with the modified gage already installed... I can't say if this is the case, the autometer gage I bought is REALLY different in that it has a brushed aluminum look to the face plate. Perhaps there is a white-faced autometer 4327? Sorry for the confusion...

[cyclone03]

TTA,
No problem.
Like I said I've never seen below 62 whatevers....

perhaps the pic with the innaccuracies was from the car being OFF and resident vacuum making the guages read slightly off.
